A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...
Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...
LED replacement bulbs include integrated driver electronics employing a variety of circuit topologies. But LED light fixtures frequently require standalone LED power supplies, sometimes called modules ...
